Yttrium barium copper oxide (YBCO) is a family of crystalline chemical compounds, famous for displaying "high-temperature superconductivity". It includes the first material ever discovered to become superconducting above the boiling point of liquid nitrogen (77 K) at about 90 K. Many YBCO compounds have the general formula YBa2Cu3O7-x (also known as Y123), although materials with other Y:Ba:Cu ratios exist, such as YBa2Cu4Oy (Y124) or Y2Ba4Cu7Oy (Y247).
Y 1415 (OTTO) Yttrium barium copper oxide, 99.9% Cas 107539-20-8 - used in many applications involving superconductors for two primary reasons, Y 1415 (OTTO) Yttrium barium copper oxide, 99.9% Cas 107539-20-8 - used as single crystals of YBCO have a very high critical current density, polycrystals have a very low critical current density: only a small current can be passed while maintaining superconductivity.
